Configuring Ethernet Port Parameters
Ethernet Network Port
A network port is network facing and participates in the service provider transport or 
infrastructure network processes. The following example displays a network port configuration:
A:ALA-B>config>port# info

mode network 
exit
no shutdown

A:ALA-B>config>port#
Ethernet Access uplink Port
Access-uplink port are network facing and transport customer service. It allows only QinQ 
encapsulation to be used. 
A:ALA-B>config>port# info

Ethernet Access Port
Services are configured on access ports used for customer-facing traffic. If a Service Access Port 
(SAP) is to be configured on a port, it must be configured as access mode. When a port is 
configured for access mode, the appropriate encapsulation type can be specified to distinguish the 
services on the port. Once a port has been configured for access mode, multiple services may be 
configured on the port.
The following example displays an Ethernet access port configuration :
